wireless controller

Remember those old wireless controllers made for the consoles of our youth like the NES and Super Nintendo? They didn’t work well, mostly owing to the fact they were built using the same infrared technology that is found in a remote control. Now that all the modern consoles are wireless, [micro] over at the nftgames forum decided to update his classic systems for wireless control.

The transmitters and receivers are built around an nRF24L01+ radio module that operates in the 2.4 GHz band. [micro] has the process of converting his controllers down to a science. He cuts the cord and wires the controller up to an AVR running at 16 MHz. The AVR sends this to the receiver where the button presses are sent through the original controller port. Basically, [micro] recreated a WaveBird controller for his NES, SNES, Saturn and N64.

The controllers are powered by internal lithium batteries, but the charging ICs are too expensive to put in each controller. To solve this problem, [micro] crafted a small external charging circuit that plugs into a 3.5mm jack on each controller. Check out [micro]’s controller demo after the break.

If you’re one of the hordes whose Xbox 360 died the fiery death associated with the RRoD you may be wondering what to do with that multi-hundred dollar door stop you’re left with. Why not salvage the parts for other uses? If you’ve ever wanted to use your wireless controller with a computer here’s a way to pull out the RF module and reuse it.

The concept is simple enough, there’s a daughter-board in the Xbox 360 which hosts the RF module for wireless controller connectivity. Once you extract it from the carcass of the beast, you just need to find a way to read and push the data to your computer. Any USB enabled microcontroller will do, in this case an Arduino nano was chosen for the task. A bit of level converting was necessary to interface with the device, but nothing too involved.

It sounds like at first there was an issue with syncing a controller with the hacked module, but as you can see in the clip after the break that problem has been solved.

Reader, [Fox9p3400], opened up an Xbox 360 controller battery pack so we could all see what goes into one. It contains two Sanyo 2100mAh NiMH AA rechargeables (Model HR-3U 1.2V). In addition to that, there is an Atmel microcontroller (not pictured) and the copper temperature probe you can see above. He has more pictures on Photobucket.
